specification of Lettera Patent.

Application filed November as, 1912. Berial No. mazes.

of my invention is to provide effective machine for this purose, ofgreat capacity, and accurate in its work, having in regard,particularly, the nature of bunting and the uses to which it end myinvention conmachine which I shall now fully describe by reference tothe ac; companying drawings, in which- Figure 1 is a plan of myinvention. Fig. 2 is a vertical section on line l y of. Fig. l.

1 is a stand or table from which rise the end plates 2 which carry theseveral parts of the'machine. Suitable tie rods 3 hold and stiffen theend plates.

In the front of the machine is one of the feed reels consisting of ashaft 4 to revolve between the end plates 2. The means for mounting thisshaft 4 are designed to permit its free revolution and to allow it to beremoved and to be replaced with facility. These means comprise a chuckshaft 5 mounted to revolve in a hearing 6 in one end plate 2, said shafthaving a clutch tongue 7 detachably engaging a groove 8 in one end ofthe reel-shaft l; and a tail-stock shaft 9 With pointed end revolublysupporting said reel-shaft at its shaft being slidbearing 10 in theother end plate 2, and held in to its work by a 11 housed in a sleeve12. A handle 13 on the outer end of the tail-stock shaft enables it tobe drawn back sufficiently to release the reel-shaft 4; when desired. Itmay be stated at this point that all the other reel and spool-shafts inthe machine are sists in the novel similarly mounted; in view of whichthese I rods is a triple guide mounted partsneednot again bespecifically described, though for the sake of clearness they aredesignated by the same numerals in so far as they appear in thedrawings.

14 is a second feed-reel, a little above and back of the first feed-reel4.

In the lower front of the machine is a guide rod 15. In the upper frontof the machine is a. guide rod 16 mounted in the end plates 2..Immediately back of and parallel with the guide-rod 16 and in a slightlylower plane is another similarly mounted guide-rod 17 separated from thefirst by a slight space and constituting with said first the front pairof guides. Slidably mounted upon the guide-rod 16 are the edge-guides 18for the edges of the cloth. These are fitted with set screws 19 in theirhubs, to fix themin whatever position they are set. These guides 18 arehere shown as disks,

and by being slotted, as indicated at 18,

upon the adjacent rod 17 of the front pair oi" guide rods, they servethe further purpose of holding and stiffening the rods in theirparallelism. Beyond and in a little higher plane than the front pair ofguide compris ng a rod 20, another rod 21 somewhat higher and fartherbark, and a third rod 22 still farther back and slightly lower than therod 21. These" are spaced apart and parallel and are carrind by andbetween the end plates 2. Edge guides 23 similar to those 18 heretoforedescribed, are adjustably mounted on the guide rod 20. I

Carried by and between the end plates 2 is the lmifc-holdcr bar 24,detachably held by a thumb-screw 25 at one end. Upon this bar areslidahly fitted the knife-holders 26 fitted with set-screws 27 by whichtheir position can be defined and regulated. These holders carry theknifc-blades 27, and these latter lie in a plane between the front guiderod pair and the triple guide, and they intersect the path of thecloth-from the former to the latter guides. Secured to the end lates 2is a spreader 28. This lies be yon' the front pair of guide rods, but inadvance of the knives. It consists of a. smooth dull edged plate or barand is so Patented Apr. 22, 1913.

located that the cloth from one feed-reel passes under it and the clothfrom the other feed reel passes over it so that the two cloths aredirected and presented to the knives in a separated or spaced relation.

At the back of the machine, carried by and between the end plates 2 arethe strip-re ceiving spools. -There may be two or more of these; threeare here shown. Each comprises a shaft and end flanges or heads mountedadjustably on the shaft. One shaft 29 is mounted in theupper portion ofthe and plates another 30 is similarly mounted in the lower portion ofsaid plates, and the :third 31 is mounted between the other two,

so that said spools lie in different horizontal planes, in verticalseries. The end flanges or heads 32 are slidable on their shafts andeach is fitted with a thumb screw 33' to establish its position asdesired. The clutch shaft 5 of the middlespool-shaft 31 is fitted with adrive pulley 33 on its outerend. Said shaft has also a -year 34 whichabove meshes with a gear 35.01: the clutch shaft 5 of the upperspool-shaft 29 and below with a gear '36 on the clutch shaft 5 of thelower spoolshaft 30. Thus the strip receiving spools are driven inunison. a

In order to impose upon the feed-reels, a tensionor pressure sufficientto retard and equalize their revolutio'nas the cloth is'unwound or paidout from them, I have a spring 37 in a bracket 38'mounted on one of theend plates 2. This spring bears upon the clutch shaft 5 and is heldthereto with regulatable pressure by a thumb screw 39. There is one ofthese tension devices for each I feed-reel.

The operation is as follows :-It will he noted that the machine asillustrated is fitted for two separate rolls of hunting. One of these4.0 is carried by the first fced-reel 4: and the other 41 by the secondfeed-reel 14. The, particular purpose of this double feature isnotmcrely to double the capacity of the machine but to enable it to cutsimultaneously into strips two rolls of bunting one of one color and theother of another color, which is particularly of advantage in themanufacture of flags, a use to which hunting is most commonly put. Letus say one of the rolls is white and the other red, as applicable to theU. S. flag, and consider that the white roll 40 is on the first reel 4:and that the redroll 4-1 is on the second reel 14:. Now tracingbyreference to Fig. 2, the

1 course of the cloth of the white roll 10,'it

will be seen that it extends from its reel 41 to the guide rod 15, andover said rod to and in contact with the upper surface of the higherguide rod'16 of the front pair of guides, its edges being accuratelyguided by the edge guides 18 on said rod. Thence it passes upon aridover the upper surface of the spreader 28, and thence to the knifeblades27 which intersect its path and cut it.

into strips, here shown as three strips.

Thence these three strips pass to and between the rods 21 and 22 of thetriple guide, beingguided thereto by the edge-guides 23 on the rod 20.The strips pass thence one to the upper receiving spool 29, a second tothe middle receiving spool 31, and the third to the lower receivingspool 30. Tracing now the course of the cloth of the red roll 41,

it passes from its reel 14 to and betweenthc guide rods 16 and 17 of thefront pair, lying in contact with the upper surface of the lower one 17of the-pair;. its edges being guided by'the edge-guides 18. passes underthe spreader 28 and thence past the knife-blades '27 which cut it intothree strips. Thence these strips pass over the rod 20.01 the, tripleguide, and thence they are carried each to the same receiving spool towhich the corresponding overlying white strip was carried, so t at uponeach receiving spool -is wound a w: itestripand a red strip, ofcorresponding size rand adapted when taken together to the sewingmachine to be easily and accurately sewed together. In this operation itwill be noted that the two cloths and their strips fare kept outof'contact throughout, until they wind together upon the receivinspools. This is of great advantage in handling fugitive ma- Thence itterial like bunting. It prevents crawling which is sure to resultfromcontact, and enables each cloth to be separately and accuratelyguided with such precision that the knife-blades will follow a singlethread and not cross it, thereby avoiding the tendency of the strip tostretch stretching being sure to result from anythingbut an absolutelystraight out, such an untrue cut, for example, as follows the attempt tocut bunting by hand. ,The' several adjustments of the edge guides and ofthe knives provide for this accuracy of operation and also determine thewidth of the strips, while thd number of the knives determine the numberof strips v into which the cloth is cut.

The advantage of mounting the several receiving spools in differenthorizontal posi tions is not only to insure the independence of thestrips without further guidance, bu'talso by spreading them out behindthe cutof details, such as may occur to those skilled in the art, may bemade without afi'ecting the principle and operation of the machine.
